SPECIFICATION forming part of Letters Patent No. 266,176, dated October17, 1882. Application filed February 6, 1882. (No model.)

To an whom z't may concern:

Be it known that I, W'ILLIAH J. MOOAUS- LAND, a citizen of the UnitedStates, residing in Philadelphia, Pennsylvania, have invented certainImprovements-in Stock Telegraph-Instruments, of which the following is aspecification.

My invention relates to certain improvements in that class oftelegraph-instruments which are used tbrrecordingstock-quotations, ac;and the objects of my invention are to prevent interference with themovement of the type-wheel due to too long a contact of the stripofpapertherewith, to provide for the definate feeding of the paper strip, topreventthe derangement of the instrument by the pulling of said strip,and to provide simple means for bringing the type-wheel to the zeroposition after the sending of a message, and for shifting theprinting-block from the letters to the figures on the type-wheel.

in the accompanying drawings, Figure 1, Sheet '1, is a vertical sectionof sufiicient of a stock telegraph-instrument to illustrate myinvention; Fig. 2, a plan view of the same; Figs. 3 and 4, Sheet 2,sectional views of a portion of the instrument, with the parts indifi'erent positionsfrom those shown in Fig. 1 Fig. 5, an enlargedsection ofthe strip-retaining 3o device; Fig.6, a modification of partofthe invention, and Fig. 7 to 15, inclusive, Sheet 3,

detached views ofthe devices for bringing the typewheel to the zeroposition and for shift ing the printing-block.

A is the base of the instrument, to suitable standards on which areadapted it rock-shalt, a, and thejournals of a type-wheel, B. Hung tothe rock-shaft a so as to be free to vibrate thereon, is a frame, 1),comprising suitable t side plates and transverse connecting-bars. To

hearings in this frame Dare adapted the ends of the fulcrtnn-bar b of alever, E, one arm of which carries a rock-shaft, d, the oppositearm ofthe lever being bent to accommodate the rock-shaft a, and beingconnected to a finger, F, which is hung to a transverse bar, 0, of theframe, and is adapted to engage with a lug,f, on the rock-shaft a, aspring, g, acting on the linger and tending to maintain the same inengagement with the lug f. Thetype-wheel B has two rows of type, one rowcontaining the letters ofthe alphabet and the other containing thenumerals and fractions used in recording stock-quotations. Therock-shaft d has two blocks, 1 2, one of which is adapted to be used inconjunction with the letters and the other with the numerals on thetype-wheel, the blocks being brought into action alternately, asdescribed hereinafter, so as to record either letters or figures in theprinted message. The rock-shaft a carries the armature w of theeleetro-magnet 1, whereby the frame D is operated, as describedhereinafter.

The strip of paper on which the message is to be printed is drawn from aroll, G, and after passing under a yoke, h, on the frame D, and betweenthe type-wheel Bandimpressionblock, is acted upon by a feeding devicecomprising a spring-plate, t, with slot at, and a pivoted arm, 75, withpin 11-, adapted to the slot at of the plate '5, the end of said platebeing bent so as to bear against a lugfl), on the frame and confine thepaper. At the end of the frame I) is a stud, 8, having a projecting pin,t, and on the base A is a post, to, in the upper end of which is a slot,10, adapted for the reception of the pin tot the stud s. A simpleopening in the top of the post may take the place of the slot, however.

I have not shown in the drawings the devices for operating thetype-wheel B, as these are similar to those usually employed, and formno part of my invention. In description it will be sufficient to saythat the type-wheel is intermittently rotated or partially rotated, soas to bring the desired letters or characters in succession above the imm ssion-blcck of the rock-shaft d on the frame D, the latter beingoperated and the strip of paper fed forward in the intervals between theoperation ofthe type-- wheel. 1

Usually the frame D is secured to the rockshaft a, and as a consequencethe impressionblock on each operation of the frame holds the paper incontact with'the type-wheel until the magnet 9 ceases to attract thearmature .r. It frequently happens that the armature is held by themagnet for some time after it should have been released, and thetype-wheel is prevented from turning by contact of the paper therewith,the result being the derangement of the operating mechanism and therendering of the message unintelligible. The construction which 1 adoptprovides for the release of the frame D before the armature x reachesthe limit of its movement toward the magnet 3 so that the retentionofthe armature will not prevent the proper rotation of the type-wheel.This result is effected as follows: When the frame D is in the positionof rest, as shown in Fig. 1, the paper is free from contact with thetype-wheel, and the latter can be rotated. The finger F engages with thelug f on the rockshaft, and serves to lock the frame D thereto, so thatwhen a current-passes through the magnet y and the armature a; isattracted the frame D is vibrated with the rock-shaft to untiltheimpression-block ontherock-shaft d presses the paper against thetype-wheel, when, the movement of the frame D continuing, the shaft (1will be depressed and the lever E will he operated so as to lift thefinger F free from the lug], as shown in Fig. 3, whereupon the frame Dwill at once fall to its original position, as shown in Fig. 4, and thetype-wheel will be free to turn. Lugs q are formed on the side bars ofthe frame I) to prevent the undue depression of the rock-shaft (I. \Vhenthe armature is released from the control of the magnet the rock-shaft ais restored to the position shown in Fig. 1 by means of a suitablespring or a counterweight, as shown in Fig. 2. On each vibration of theframe I) the strip of paper will be fed forward to a certain extent,owing to the action of the arm 7.". and plate 17, the elevation of theplate causing the arm to swing outward, so that the pin it traverses theslot at and carries the paper with it, as shown in Fig. 3. On thedownward movement of the plate the pin it is withdrawn from the paperandthe arm 7; swings back to its first position, as shown in Fig. 1.

The plate t is bent, as shown, so as to prevent an undue elevation ofthe end of the arm 7. A plate, rigidly secured to the frame .I) andhaving a slot, in, may in some cases take the place of the spring-platei; but the use of the latter is preferred, as it permits the clamping ofthe paper between the end of the plate and the projection p, and thusprevents-the pin n from drawing the paper backward on the downwardmovement of the plate i.

When the frame D is in the position of rest, as shown in Figs. 1 and 4,all movement of the strip of paper is prevented, owing to the pin tofthe stud s, and by this means I overcome a serious objection to theordinary form ofstock telcgraph-instrnment, said objection being theliahility ot' the mechanism to derangement caused by bringing the paperinto contact with the type-wheel while the strip is being pulled throughthe machine by an observer, a partial turning of the type-wheel beingthus effected, so that it does not accord with thetransmitting-instrument.

Various modifications of the mechanism for releasing the frame I) fromthe control of the rock-shaft a may be devised Within the limits of myinvention. For instance, instead of the spring-finger F, the lever mayhave a lag, z,

adapted to engage with a lug,f, on the rock shaft and a-lug,f, on theframe J), as shown in Fig. 6, the lug .0 serving to lock the frame 1) tothe rock-shaft so long as it engages with the lugs ff, but the framebeing freed from the control of the rock-shalt as soon as the said lug zis lifted from between the lugsff.

The devices for bringing one impressionblock after the other intooperation, so as to print either letters or figures on the strip ofpaper, are shown in Figs. 7 to 10, Sheet 3, and comprise arms 3 4,secured to the rock-shaft (I and adapted to be acted upon by a lug, 5,-on the type-wheel. Thus when the rock-shaft is in the position shown inFig. 7 the impressionblock 1, which acts in connection with theletter-row of the type-wheel, is uppermost and in use, the block 2,which acts in conjunction with the numeral-row, being depressed.

\Vhen it is desired to print numerals instead of letters, the type-wheelis moved to the position shown in Fig. 7, so that on the elevation ofthe rock-shaft the lug 5 will strike the arm 3, as shown in Fig. 8, andthus cause a partial rotation of the rock-shaft, so as to bring theblock 2 uppermost and throw the block 1 out of use. The reversal of thisoperation is offected by first bringing the type-wheel into the positionshown in Fig. 9, so that the lug 5 is in line with the arm 4, whereuponon the elevation of the rock-shaft by the frame I), the lug will comeinto contact with said arm 4, and will depress the same and partiallyrotate the rock shaft. The action of the lug 5 on the arms 3 and atsimply commences the movement of the rock-shaft, the completion of themovement being due to the action of a spring-plate,ti, upon a lug, 7,carried by the rock-shaft, the action of the spring being to impart anabrupt movement to the shaft as soon as the lug has passed the centerline in one direction or the other. The lug and spring also serve as ameans of retaining the shaft in either of its extreme positions, as willbe readily understood on reference to Figs. 7 and t). g

In working telegraph -insiruinents of the class to which my inventionrelates itis usual, after completing a message, to cause the typewheelto make two or more complete revolutions, and then to bring it to astandstill at the Zero or starting point, ready for proceeding with anew message. The means which I adopt for permitting this rotation of thetypewheel and effecting the stoppage of the same at the zero-point areshown in Figs. 11 to 1-1, and are as follows: To a pin on one of theside bars of the frame 1) is hung a sleeve, 8, from which project fourpins, 9, 10, ll, and 12, and on the type-wheel are two bent pins, 1 3and 14L, the former projecting farther beyond the periphery of thetype-wheel than the latter. The pin 11. of the sleeve 8 is also longerthan the pins 9 and 10, and is furnished at the end with a lug, 15. Thenormal position of the sleeve 8 and its pins is that shown in Fig. 11,and the sleeve is restored to thisposition on each elevation of theframe D by the action of a bent rod,. 16, on the pin 12. When thetype-wheel has several revolutions imparted to it, however, without anyoperation of the frame D, the result will be that the pin 13 will firststrike the pin 9 and partially turn the sleeve. On the next rotation ofthe wheel the pin 13 will strike the pin 10, as shown in Fig. 12, andstill further rotate the sleeve, and on the third turn of the type-wheelthe pin 14 will strike the lug 15 of the pin 11, and will be heldthereby, as shown in Fig.13, the sleeve being prevented from turningfurther by a suitable stop. The pin 12 then occupies a position so farremoved from the bent end of the rod 16 as to permit a slight elevationof the frame D before said pin will come into contact with the bent endof the rod, and this movement is sufficient to free the pin 1.4 of thetype-wheel from the control of the lug 15 of the pin 11, so that uponcontinuing the upward movementoftheframe D the sleeve 8 will be restoredto its original position by the action of the bent rod 16 on the pin 12.In printing the message each revolution of the typevw'heel will effect apartial rotation of the sleeve 8, owing to the action of the pin 13 uponthe pin 9; but, as after each separate operation of the type-wheel thereis an operation of the frame D, the sleeve 8 will be thereby restored toits normal position and will not interfere with the movements of thetype-wheel necessary in transmitting a message.

In order to prevent undue movement of the sleeve 8 by the action of thepin 13 upon the pins 9 and 10, I employ a spring, 17, which acts uponflattened portions of the sleeve and serves to retain the same in thepositions to which it is adjusted.

In Fig. 15 l have shown a modification ofmy invention, in which the pin14 is dispensed with, all of the pins 9, 10, and ll acting inconjunction with the single pin 13 on the typewheel, the length of thepin 11 permitting the pin 13 to pass beyond the center line of thetype-wheel, as shown, so that it will be out of the path of the pins 9and 10 as the frame D is elevated and the sleeve 8 rotated.

I claim as my invention- 1. The combination, in a telegraph-instrument,of the pivoted frame D and. impressionhlock, the type-wheel B, therock-shaft a, act-- uated by a magnet, and a device for clutching theframe to and releasing it from the said rock-shaft, all substantially asspecified.
